Capital general manager David Poile will have to use his diplomatic skills to smooth over relations with his Russian contingent.Restricted free agent Alexander Radulov and unrestricted free agent Andre Kostitsyn sat for two games of the ill-fated Coyotes series after missing a team curfew. Restricted free agent Sergei Kostitsyn made curfew but wasn’t happy with how coach Barry Trotz treated the other two.“I think the management was too tough on Alexander and Andrei,” told a Russian publication, according to a translation by Dmitry Chesnokov of Yahoo! Sports. “The punishment for the incident could have been a monetary fine, [they] went too far with the disqualification in the midst of an important stage of the playoffs. We missed the guys in games three and four of the series.”The Predators could likely get something for Radulov’s rights, if Poile opted to turn that page. Several franchises would love to add Radulov’s talent, assuming he still wants to play in the NHL.Nashville could let Sergei Kostitsyn walk by opting not to make him an offer. Andrei Kostitsyn is free to weigh anything the Predators might offer against potential deals elsewhere.Can the relationship be salvaged? This trio could increase Nashville's offensive skill level by sticking around.
